IMPROVEMENT IN CAR-COUPLINGS.

Specilication forming part of Letters Patent No. 150,031, dated April21, 1874 application tiled4 July 26, 1873.

To all whom it may concern:

Be it known that I, VILLIAM H. HAMMOND, of Syracuse, in the county ofMorgan and State Of-Oliio, have invented a new and valuable Improvementin Oar Couplings, and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings making a part of thisspeciiication, and to the letters and li gures of reference markedthereon.

Figure l ofthe drawings is a representation oi' my invention inlongitudinal vertical sec tion, and Fig. 2 is a plan view of the same.

l\I y invention relates to devices for coupling two railroad-carstogether; and it consists in a drop or gate with cam projection, and aspring arranged in the center chamber of a three-chambered bumper, ashereinafter more fully described.

In the accompanying drawing, like letters indicate corresponding parts.

A A represent the draw-heads or bumpers oi' two adjoining railroad-cars,each of which is divided by two vertical partitions, a a, into threecompartments or chambers. The side chambers are each provided with apin, B, and link O, for use as the ordinary pin and link coupling. Inthe root at the front end of the center chamber is hinged a drop orgate, D, which extends toward the rear, and is pressed downward by meansof a spring, b. The drop D has a rod, d, attached to it, whereby it caneasily be raised when it is desired to uncouple the cars, said rodextending up to and through the platform of the car, or to the top ofthe same, according to as it is a passenger or freight car. E representsa longitudinallyslotted pla-te or bar, provided at each end on the upperside with a projection or head, G, the

transverse sectioncf which is an inverted V, as shown in Fig. l.

It will readily be seen that this bar, being forced into the centerchamber of the drawhead, will raise the drop or gate D, and as soon asthe head has passed the spring b forces it down in front thereof,thereby coupling the cars.

If either car should, by any accident, be turned over, the bar E willraise the drop and pass out.

The side links C C, when used in connection with the center coupling,prevents any unnecessary lateral motion of the cars. By having the bar Ecrooked or bent, cars of unequal height may be coupled; and a car withthis coupling may be coupled to a car with the ordinary pin and linkcoupling.

rlhe back of the gate D is provided with a canrprojection, z, for theend of the spring b to ride upon. Friction is saved by this means, andthe action of the spring intensilied as the gate is raised.

What I claim as new, and desire to secure by Letters Patent, is-

The drop or gate D having cam projection e, in combination with thespring b andthe slotted bar E having heads G G in the bumper A,substantially as and for the purposes herein WILLIAM HENRY HAMMOND.
